ABSTRACT
This is a prospective study of 21 patients [27 kness] underwent primary total knees arthroplasty without patellar resurfacing, using a conforming femoral design [profix components]. All patients had a diagnosis of osteoarthritis and followed for an average of 2.5 years. No major complications occurred and no patellar revision was required by the 2.5 years postoperative follow up. 89% of the cases were able to climb stairs without support. Two Knees [7%] had mild anterior knee pain with stair climbing only. Patellar tendon length was shorter in patients who had anterior knee pain than in patients who did not. There was no statistically significant correlation found between postoperative anterior knee pain and clinical score, decrease of patellar cartilage thickness, severity of patellar disease or patellar bone quality, indicating that unresurfacing of the patella in total knee arthroplasty with conforming femoral design has significant outcomes and avoid complications of resurfacing the patella
